BYRON COBURN, OF OARDWELL, VIRGINIA.

MACHINE FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 443,132, dated December23, 1890.

Application filed September 9, 1890- Serial No. 364,401. (No model.)

To all whom it may concern:

Be it known that I, BYRON OOBURN, a citizen of the United States,residing at Cardwell,in the county of Goochland and State of Virginia,have invented a new and useful Machine for Converting and TransmittingMotion, of which the following is a specification.

This invention relates to machines for converting and transmittingmotion; and it has for its object to construct a device of this classwhich shall be simple, durable, and efficient in operation, and wherebythe reciprocation of the hand-levers with which the machine is providedmay be converted into rotary motion, which may be used for driving smallmachinery.

YVith these ends in view the invention consists in the improvedconstruction, arrangement, and combination of parts, which will behereinafter fully described and particu larly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a plan view of a machineembodying my improvements. Fig. 2 is a side elevation of the same. Fig.3 is a vertical transverse sectional view.

Like numerals of reference indicate like parts in all the figures.

The frame of my improved machine is preferably rectangular in shape, andthe upper longitudinal frame-beams 1 1 are provided with boxes orbearings for the transverse shafts 2 and 3, the former of which carriesat its outer end a spur wheel 4:, meshing with a segment 5, which ismounted upon the outer end of the shaft 3, and to which is attachedahandle or lever 6, by means of which it may be conveniently manipulated.The shaft 2 also carries a drum 7, having flanges 8, which extendpartially around its circumference, and which serve to guide therope orcord, chain, belt, or the like 9, which is wound upon and secured bymeans of staples or in any other convenient manner to the perimeter ofthe drum-pulley in such a manner as to positively prevent its slipping.The ends of the rope or equivalent 9 are passed over pulleys 10, whichare journaled upon shafts 11 at the ends of the frame.

The outer side beams of the frame are provided with longitudinalbrackets 11, consisting of circular rods 15, the outer ends of which arejournaled or mounted in boxes 12 upon the legs or uprights 13 at theends of the frame, and the inner ends of which have elbows 14; extendingthrough the framebeams and are secured by means of nuts and washers. Thelongitudinal rods 15 serve as guides for the longitudinally-slidingboxes 16, which are provided at their upper and lower ends with sleevesor bearings 17 for the said rods. The boxes 16 are also provided withcentrally-located sleeves or collars 18, which are connected by means ofa longitudinal rod 19, which, in conjunction'with the sliding boxes 16,forms a longitudinally-reciprocating frame, the ends of which aresuitably connected with the ends of the rope or belt 9, passing aroundthe drum or pulley 7. One of these sliding boxes 16 is provided with alaterally-extending bracket 20, to which is pivotally connected a pitman21, the free end of whichis connected with a crank 22, formed at one endof the shaft 23, journaled transversely in the frame and carrying afly-wheel or balance-wheel 2a. The shaft 23 may also carry an additionalwheel or pulley 25, from which motion may be transmitted by means to bedriven.

From the foregoing description, taken in connection with the d rawingshereto annexed, the construction and operation of my invention will bereadily understood. The operator, by manipulating the lever or handle 6,may impart an oscillating motion to the wheel or drum 7 upon the shaft2, and thus transmit a reciprocating motion to thelongitudinallyremovable frame composed, essentially, of the end piecesor head-blocks 16 and the connectingrod 19. The said frame in itsreciprocatory movement actuates the pitman 21, and thus transmits arotary motion to the shaft carrying the balance-wheel 24, from whichmotion may be readily conveyed to the machinery which is to be driven.It is obvious that by using a fly-wheel of sufficient size and weightsuifieient impetus may be gained to drive all kinds of moderately-lightmachinery in an easy and eflicient manner.

Instead of a single operating-lever 6, having toothed segment 5, twosuch levers may be employed, being arranged on opposite sides of thespur-wheel 4, the additional lever and of a belt or band to themachinery which is toothed segment havingbeen shown in dotted lines inthe drawings. By this arrangement two men stationed on opposite sidesmay simultaneously operate the machine.

Having thus described my invention, What I claim is 1. In a machine forconverting and transmitting motion, the combination of a rectangularframe, the longitudinal guide-rods secured to the outer sides of theside beams of said frame, the longitudinally-reciprocating framecomprising the head-blocks mounted upon the said guide-rods andconnected by a longitudinal connecting-rod, means forimpartingalongitudinally-reciprocatory motion to the said frame, and apitman connecting one end of said frame with a crank upon a shaft havinga balancc-\vl1eel, substantially as set forth.

2. In a device for converting and transmit ting motion, the combinationof the frame, the longitudinal guide-rods secured to the sides of thesame, the reciprocating frame composed of the head-blocks mounted uponsaid guide-rods and connected by a central longitudinal rod, a drum orWheel mounted upon a suitable shaft and having a belt or band passingover guide-pulleys and connected with the ends of the reciprocatingframe, a lever havinga segmental rack meshing with a spur-wheel upon thecentral oscillating shaft, and a pitman connecting one end of thelongitudinally-reciprocating frame with a crank upon the end of a shaftcarrying a fiy-Wheel, substantially as and for the purpose set forth.

3. In a machine of the class described, the combination of the framehaving the longitudinal guide-rods, the head-blocks mounted toreciprocate upon the said guide-rods and connected by a centrallongitudinal rod, means for imparting a reciprocating motion to theframe thus formed, a bracket extending laterally from one of thereciprocating head-blocks, and a pitman connecting said bracket With acrank upon a transverse shaft carrying a fly-Wheel, substantially asherein set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
